VEHICLE BUMPER.

Application filed November 29, 1927. Serial No. 236,451.

This invention relates to automobile bumpers and more particularly to a mask plate for covering the connections between the bars at the ends of the bumper. An object of the invention is to produce a bumper having a pivotal end construction of increased strength. A further object is to produce a bumper of suitable end construction to give the maximum protection and one which is at the same time attractive in appearance. A further object is to produce a mask plate to be applied to a pivotal connection at the end of the bumper. y

Further and more or less limited objects will be apparent from the following description, from the drawings and from the use of the articles covered by the appended claims.

In the drawings Fig. 1 represents a plan view of a bumper embodying my invention; Fig. 2 represents a front elevation ofthe bumper shown in Fig. 1; Fig. 3 is a detailed fractional front elevation of the end of the bumper shown in Fig. 2; Fig. l is a section taken on line 4-11 of Fig. 1; Fig. 5 is a section taken on line 5 5 of Fig. 14; Fig. 6 is a detailed fractional plan view of the end of a bumper showing a modified form of vmy invention; Fig. 7 is a fractional detailed front elevation of the end of the bumper shown in Fig. 6; Fig. 8 is a section taken on line 8-8 of Fig. 6; Fig. 9 is a section taken on line 9-9 of Fig. 6; Fig. 10 is a detailed front elevation of the ends of the impact bars used in the bumper shown in Fig. 6; Fig. 11 is a detailed fractional plan view of a bumper showing a modified form of my invention; Fig. 12 is a fractional front elevation of the bumper shown in Fig. 11; Fig. 13 is a section taken on line 13-13 of Fig. 11; Fig. 14C

is a section taken on line1414l of Fig. 11;

and Fig. 15 is a fractional front elevation of the ends of the impact bars used in the bumper shown in Fig. 11. y

In the description and claims, the impact bars will be considered as the front of the bumper and the terms front and rear will be used in view of this assumption. It is not intended, however, to limit the use of my invention to any particular position on the bumper.

Of the reference characters shown in the drawing 1 and 2 indicate theupper and lower impact bars of a bumper of the general type shown and described in the McGregor Patent No. 1,372,151 issued March 22, 1921. The

back bar 3 is connected at its ends to the ends of the impact bars and connected to, and between, the impact bars 1 and 2 by means of the clamp 4. Each of the impact bars has an eye 5 at each end and the back bar 3 has a pivot plate 6 fixed to each end, each such plate being formed to lit around the edges of an end of the rear bar and having a horizontally propecting portion 7 with an aperture therein.

The mask plate 8 is adapted to bear upon the front of the impact bars 1 and 2 and has flanges 9, 9 extending rearwardly over the edges of the bars 1 and 2 and the eyes at the ends thereof. These flanges have apertures therein in alignment with each other. The outer end of the mask plate extends around the end of the bars a sufficient distance to cover these portions.

In assembling the bumper the pivot plate 6 is placed between the aligned eyes at the ends of the impact bar so that the aperture therein is in alignment with such eyes. The mask plate 8 is'applied so that the apertures in the flanges 9, 9 are in alignment with the eyes in the ends of the bumper bars and the aperture in the plate 7 and a bolt 10 is passed through the aligned eyes and aperture and is tightened by means of a nut 11. llhe mask plates Seach have an aperture 12 in its front surface through which the bolt 13 is adapted to pass. I he bolt 13 passes through the space between the impact bars and, co-acting with the mask plate 8, the rear plate 14 and the nut 15 holds the mask plate against the impact bars. The sleeves 16 may be placed within the eyes 5 before assembling the several parts.

The mask plate S is held against longitudinal movement by means of the flanges 9, 9 and the apertures therein surrounding the bolt 10 and it is prevented from pivoting around such bolt by the clamping action of the bolt 12 and the rear plate 14. This construction permits the impact and rear bars to operate pivotally with respect to each other and the mask plate strengthens the end construction and improves the appearance of the bumper.

` In the modihed forms shown in Figs. 6 to 15 parts which are alike will be indicated by like numerals.

In the modification shown in Figs. 6 to 10 the upper impact bar 1a is cut down at its vend portion as shown at 17 and has a short j pact section may be maintained.

Asshown `more clearly'in Fig. 6 the front tace ot' theinask plate 8a extends part Way around the eye 5a to tlie'position indicated at 18. Upon the rear surface of the mask plate @there is provided a projection 19 adapted to entend betw the impact bars 1a and 2 and to bear upon the surface of the plate 7. lhere are also provided projections 20,

'extending between the impact bars 1a and y2 and adapted to keep the plate 14 troni turn-` ing.

ln this modilication the bolt 10"L does not pass through the ilange 9@ and the bail 1'a is cut down so that the smooth line ot the im- The mask plate is held against longitudinal movement by the lug 19 and by the end portion 18 ot the trent suriiace of t-lie'niask plate, and it is clamped to the impactbars bynieans oit the Vbolt 13 passingthrough the mash plate t3 andthe rear plate 14.

ln the modification shown inr F 11 to 15 the impact bars 1a anc 2a are each cut down Aas indicated at 17 and have shortened eyes 5 and may have shortened sleeves 16a therein. Flanges 9 extendrearvvardly above and bellovv the impact-'bars 1 and 2LP and theeyes therein. The bolt 10b passing 'through the eyes 5" and the aperture in the plate 7, is enclosedvvitliin the mask plate vand does not front surface oi the mask plate 8b is extended around the outside of the eyes to the point indicated at 1.8 and a lug 19 projecting between the impact bars 1?L and 2CL provides a surface adapted to bear upon the surface oi the platev 7. A lug 20h projecting between the impact bars 1la and 2? has a threaded hole therein to receive the shank of a cap screw 22. The rear plate 21 is shown as bent to bear upon the rear surfaces oit the impact 1` and 2Q and basan aperture therein lor the shank of the screw 22. V

The reduced ends ot the impact bars used in this-modification allow the use otra mar-:lt plate inv Wliichthe horizontal flanges are in. line with the upper and'loiver edges et the impact bars, tlius providin a continuous nnbrolcen line. against lateral movement by the lug 19 and the portion 18 oit the front suriface oit the plate..

It is apparent that my invent-ion may be 7n used with bumpers of varying construction and appearance and it is not intended to hereby limit its use to the particular bumper herein shown and described, it being applicable to use Wherever a pivotal connection between Vthe bars is' used.

In the construction Ih'ave shown the pivotal action between the impact and rear bars isnot interfered With but the pivotalVv construction is strengthenedv and the appear# 80V ance ot the bumper is made more attractive.
